I do live near the pond. In the spring I open the hydrant 24/7 to fill the pond from the winter draw down, which is usually about 2 ft or so, and it can take 3 or 4 weeks to fill the pond. Then I just like to run the well for maybe 6 to 8 hours at night to keep ahead of evaporation. Before I installed the pressure tank I would manually turn on the pump open and close the the fill hydrant in the evening and morning to maintain the water level. If I wanted to use the hydrant at the dock house I would have to run over to the wellhead turn on the pump go back to the dock house open the hydrant for use and then remember to go back and turn the well pump off. With a mechanical timer and the hydrants on a pressure tank I don't have to do that anymore since the timer will turn the fill hydrant off and on and I can use the dock hydrant as needed.
